Description

Developer Patrick Cozzi reported a crash in some circumstances when using the Cesium JavaScript library to generate WebGL content. Mozilla developers determined that this crash is potentially exploitable.

In general this flaw cannot be exploited through email in the Thunderbird product because scripting is disabled, but is potentially a risk in browser or browser-like contexts.
